CData Sync



Replicate multiple EnterpriseDB accounts to one or many databases.

CData Sync for EnterpriseDB is a stand-alone application that provides solutions for a variety of replication scenarios such as replicating sandbox and production instances into your database. Both Sync for Windows and Sync for Java include a command-line interface (CLI) that makes it easy to manage multiple EnterpriseDB connections. In this article we show how to use the CLI to replicate multiple EnterpriseDB accounts.

Configure EnterpriseDB Connections

You can save connection and email notification settings in an XML configuration file. To replicate multiple EnterpriseDB accounts, use multiple configuration files. Below is an example configuration to replicate EnterpriseDB to SQLite:

Windows

<?xml version="1.0" encoding="UTF-8" ?> <CDataSync> <DatabaseType>SQLite</DatabaseType> <DatabaseProvider>System.Data.SQLite</DatabaseProvider> <ConnectionString>User=postgres;Password=admin;Database=postgres;Server=127.0.0.1;Port=5444</ConnectionString> <ReplicateAll>False</ReplicateAll> <NotificationUserName></NotificationUserName> <DatabaseConnectionString>Data Source=C:\my.db</DatabaseConnectionString> <TaskSchedulerStartTime>09:51</TaskSchedulerStartTime> <TaskSchedulerInterval>Never</TaskSchedulerInterval> </CDataSync>

Java

<?xml version="1.0" encoding="UTF-8" ?> <CDataSync> <DatabaseType>SQLite</DatabaseType> <DatabaseProvider>org.sqlite.JDBC</DatabaseProvider> <ConnectionString>User=postgres;Password=admin;Database=postgres;Server=127.0.0.1;Port=5444</ConnectionString> <ReplicateAll>False</ReplicateAll> <NotificationUserName></NotificationUserName> <DatabaseConnectionString>Data Source=C:\my.db</DatabaseConnectionString> </CDataSync>

The following connection properties are required in order to connect to data.

  • Server: The host name or IP of the server hosting the EnterpriseDB database.
  • Port: The port of the server hosting the EnterpriseDB database.

You can also optionally set the following:

  • Database: The default database to connect to when connecting to the EnterpriseDB Server. If this is not set, the user's default database will be used.

Connect Using Standard Authentication

To authenticate using standard authentication, set the following:

  • User: The user which will be used to authenticate with the EnterpriseDB server.
  • Password: The password which will be used to authenticate with the EnterpriseDB server.

Connect Using SSL Authentication

You can leverage SSL authentication to connect to EnterpriseDB data via a secure session. Configure the following connection properties to connect to data:

  • SSLClientCert: Set this to the name of the certificate store for the client certificate. Used in the case of 2-way SSL, where truststore and keystore are kept on both the client and server machines.
  • SSLClientCertPassword: If a client certificate store is password-protected, set this value to the store's password.
  • SSLClientCertSubject: The subject of the TLS/SSL client certificate. Used to locate the certificate in the store.
  • SSLClientCertType: The certificate type of the client store.
  • SSLServerCert: The certificate to be accepted from the server.

Configure Queries for Each EnterpriseDB Instance

Sync enables you to control replication with standard SQL. The REPLICATE statement is a high-level command that caches and maintains a table in your database. You can define any SELECT query supported by the EnterpriseDB API. The statement below caches and incrementally updates a table of EnterpriseDB data:

REPLICATE Orders;

You can specify a file containing the replication queries you want to use to update a particular database. Separate replication statements with semicolons. The following options are useful if you are replicating multiple EnterpriseDB accounts into the same database:

You can use a different table prefix in the REPLICATE SELECT statement:

REPLICATE PROD_Orders SELECT * FROM Orders

Alternatively, you can use a different schema:

REPLICATE PROD.Orders SELECT * FROM Orders

Run Sync

After you have configured the connection strings and replication queries, you can run Sync with the following command-line options:

Windows

EnterpriseDBSync.exe -g MyProductionEnterpriseDBConfig.xml -f MyProductionEnterpriseDBSync.sql

Java

java -Xbootclasspath/p:c:\sqlitejdbc.jar -jar EnterpriseDBSync.jar -g MyProductionEnterpriseDBConfig.xml -f MyProductionEnterpriseDBSync.sql
